Abstract: 

Determination of side weir coefficient spatially varied flow with lateral out flow is considered to be one of the most important issues because it improves the accuracy of results and consequently makes the design more trustable In this study, the governing differential equations are solved by the Runge Kutta fourth order method. A nonlinear optimization technique is utilized to determine the side weir coefficient by minimizing the differences between its calculated and measured results. In this regard, many relationships for the side weir coefficient are selected. Relationships which yield better agreements among calculated results data are chosen as final ones. These relationships are compared to other relationships proposed by other investigators. The comparison indicates that the relationships proposed by this study give accords with measurements.
